The current rate control method can adjust the data transmission rate according to the congestion indicators of the ship mobile network, which can slow down the network congestion, but decline the whole network traffic, cause the transmission timeout problem, and cannot meet the network transmission fairness demand. To solve the congestion problem, a rate control method is proposed to start the corresponding rate control mechanism according to the cluster head and the congestion indicators in the cluster. The sum of the node utility functions in the maximized cluster is taken as the objective function of optimization. According to the congestion degree of the network feedback, the source data transfer rate is constantly adjusted, which can achieve the fairness of resources sharing ratio between nodes. Experimental results showed that the proposed method can effectively alleviate network congestion and reduce the transmission delay.
